/* AtlasLatino — hand-written CSS, no framework.
   Design system "B2": a structured research index. IBM Plex Mono for
   metadata (nav, dates, field labels, link buttons), IBM Plex Sans for
   titles and body prose. A left metadata rail forms a scannable vertical
   spine down the page; hairline rules separate entries. Dark warm-grey
   palette with a terminal-green accent. No gradients, no icon fonts.

   Contrast, measured on each surface text actually renders on
   (--panel #302d29 cards / --paper #1a1917 page background):
     --ink       body text     11.7:1 / 14.9:1
     --ink-soft  prose          8.6:1 / 11.0:1
     --gray-700  muted          6.2:1 /  8.0:1
     --gray-500  muted small    5.3:1 /  6.8:1
     --accent    links         10.1:1 / 13.0:1
   --gray-350 is NON-TEXT only: field-square fallback, separators, borders. */

  /* Dark warm-grey palette (not blue-black, so it stays in the same
     family as the earlier light theme, just inverted).
     Cards sit on a lighter warm grey than the page, same relative
     logic as before: --panel is always the brighter surface, --ink
     always the text color, so anything relying on that relationship
     (e.g. .entry[open] .chevron using --ink as a fill with --panel as
     the glyph color) still works unchanged.
     Every text color clears 4.5:1 on BOTH surfaces it might render on —
     muted text is brightened further than a literal desaturation would
